 La investigación se realizó en la granja experimental Manglaralto, propiedad de la Universidad Estatal Península de Santa Elena, ubicada en las coordenadas UTM 528944m E y 9796468m S zona 17M datum WGS-84 a 12 msnm, con una topografía inferior al 1%, la investigación tuvo como objetivo determinar el comportamiento productivo de clones de café robusta (Coffea canephora P.), de alta productividad en las condiciones agroecológicas, de Manglaralto Ecuador. Para el establecimiento del ensayo, se utilizaron 23 clones de café robusta, seleccionados por COFENAC en la región amazónica del norte de Ecuador. Los clones fueron dispuestos al azar, cada clon es una unidad experimental representada por 20 plantas, sembradas a una distancia de 3 x 3 metros. Los resultados preliminares se sometieron al análisis de estadística descriptiva, determinándose medidas de tendencia central y de dispersión media aritmética, desviación estándar, coeficiente de variación, entre clones y dentro de los clones. Sin embargo, al cuarto año, se destacan como promisorios en producción los clones 1, 4, 5, 6, 14, 15, 16 y 18. El comportamiento productivo es muy alentador considerando que el clon 1 obtuvo producción de 61 quintales y el clon 15 alcanzo 39,3 quintales de café oro por hectárea, los demás clones enunciados obtienen producción promedio de  42 quintales.AbstractThe research was carried out in the experimental farm Manglaralto, owned by the Peninsula State University of Santa Elena, located at the coordinates UTM 528944m E and 9796468m S zone 17M datum WGS-84 at 12 msnm, with topography of less than 1%, research (Coffea canephora P.), high productivity in the agroecological conditions of Manglaralto Ecuador.

Introduction: A school is where a student learns and molds into the desired individual but sometimes, a place where the famous and beautiful are honored and respected while the poor little ones are experience bullying. This study aims to determine the perceptions and prevalence of bullying to design a plan addressing issues on students' predicaments in Biliran Province State University (BiPSU).Methods: The researchers made use of the Statistical Package for the Social Sciences (SPSS)-Descriptive Statistics’ frequency, percentile and central tendency, where variables as to profile, perception and prevalence of  bullying among secondary students  are statistically analyzed.Results: Students' perception of bullying is significant than its prevalence. Students have increased knowledge and awareness of bullying. However, though less notable than the perception, the pervasiveness of bullying is still considerable.Conclusion: The majority of the respondents have not experienced bullying. Students think that bullying at school happens once or twice a term. Student's perception of bullying is more eminent than its prevalence. These pervasion results are meaningful because students' reflection in bullying is distinguished.

The development of an agro-industrial complex under present-day conditions is impossible to imagine without the development of agro-biotechnology, which in turn requires specialists with profound knowledge of biology, chemistry and related sciences. In this regard, training of personnel is needed to ensure active implementation of modern technologies in agricultural sciences. Until recently, such specialists have not been trained at classical universities, to which St. Petersburg State University belongs. To deal with this challenge, a Masters Program «Molecular Biology and Agrobiotechnology of Plants» has been developed and is being implemented in SPbSU. Teaching staff from eight departments of the Biological Faculty of SPbSU is involved in the creation and implementation of the Program. The Program in question is focused on familiarizing students with the modern problems, achievements, methodology of agro-biotechnology of plants, as well as on practical application of the obtained knowledge. Special attention is paid to the formation of trainees’ perceptions of the possibility and necessity of bringing plant breeding to the level of requirements and possibilities of the «post-genome era» to achieve high productivity and sustainability of agricultural production with minimal environmental risks. The Program seamlessly integrates practical exercises and students’ research work in the SPbSU facilities, as well as that performed at St. Petersburg research institutes. Much attention is paid to the development of students’ skills in conducting scientific discussions and in presenting their scientific data in different formats, for instance in English, which is very important for monitoring current scientific trends and integrating own research into world science. The Program is popular with students and many of its graduates have been employed by the leading biological and agricultural research institutes.

Objective: To explore the perceived attitudes toward continuing education and the deterrents to continuing education for certified athletic trainers (ATCs). Design and Setting: Data were collected using the Adults Attitudes Towards Continuing Education Scale (AATCES) instrument, Deterrents to Participation Scale-General (DPS-G) instrument, and self-reported demographics. Subjects: An imbedded on-line questionnaire was e-mailed three times in a 6-week period to ATCs who subscribe to the athletic trainers listserv at Indiana State University and the professional athletic trainers education listserv at Findlay University. The sample of this study consisted of approximately 1,200 ATCs of which 268 answered and returned the survey, a return rate of 22%. Measurements: Data included descriptive statistics, a one-way Analysis of Variance (ANOVA), and Cluster Analysis to compare the demographic groups on the AATCES and the DPS-G instruments. Results: This study found that the participants have a very positive attitude toward continuing education according to the AATCES instrument and that the participants report few deterrents through the DPS-G instrument. However, two deterrents of statistical importance were found in the items related to Time and Course Relevance and one deterrent, Cost, was found in the comparison to gender.Conclusions: This study found that ATCs have a very favorable attitude toward continuing education and that ATCs perceive few deterrents to continuing education. To further understand these trends in continuing education, these particular surveys must be made available to more ATCs. In addition, continuing education providers need to understand the needs of the ATCs that they serve.

<p>The objective in this study was to evaluate the spatial and temporal variability of the beverage quality by applying the fuzzy classification in the final global sensory analysis, for Coffea canephora Pierre ex A. Froehner, in two consecutive harvests. The studied variables were: fragrance (aroma), flavor, bitterness (sweetness), set, balance, cleaning, aftertaste, mouth feel, uniformity, salinity (acidity) and drink (global note). To the average overall scores of the drinks obtained on the cup-tasting at 80.0 points of a sampling, the mesh has applied the function of association of the fuzzy classification linear model to determine the degree of pertinence. The data were analyzed by the descriptive statistics and then by geostatistics to verify the existence and quantify the degree of spatial dependence of the variables. In the interval classified as “very good coffee” is found in the global average grade, in the two harvests. The methodology fuzzy applied in the global beverage note of the coffee conilon seminal made it possible to determine their spatial variability in the same distribution pattern in the two harvests, close ranges, and adjustments to the spherical model, which was confirmed by the spatial correlation of 61.6% among the fuzzy maps for the global score</p>

El presente estudio guarda estrecha relación con la alimentación de caprinos, las ganancias de peso y su producción; sabiendo que, para que un animal logre buenos rendimientos productivos se hace necesaria una alimentación que cubra necesidades energéticas de mantenimiento, luego de crecimiento y ganancia de peso o de producción; se determinó el recorrido en unidades de desplazamiento; luego, por medio de fórmulas de medición energética trasformar esto a energía metabolizable que es una unidad fácilmente relacionable con las necesidades energéticas de mantenimiento y de producción, siendo 60 cabras de diferentes razas las que se consideraron en este estudio, donde se registró su peso, y edad antes de que formen parte del ensayo. Con la ayuda de podómetros calibrados para usarlos en cabras, se determinó el recorrido habitual. Los podómetros fueron colocados en uno de sus miembros posteriores a la altura de la rodilla, y retirados 24h después, registrando su desplazamiento y actividades en busca del alimento. Utilizando Excel se procedió a la tabulación y organización de los datos, que fueron sometidos a estadística descriptiva y análisis de la información, como resultado se evidenció 5Km de recorridos por animal, con edades entre 2,5 años de promedios, de igual forma las razas de cabras más frecuentes fueron, en primer lugar la Criolla y en segundo la Nubia; ambas razas de animales no se diferenciaron en el recorrido y peso, lo que permitió utilizar una forma universal de estimación del gasto energético (0,49 kcal/kg /km) pudiéndose determinar que fueron 87,69Kcal involucradas en 24h de actividad. ABSTRACT This study is closely related to feeding goats, weight gain and production; knowing that, for an animal to achieve good production yields a feed that covers maintenance energy requirements is necessary , after growth and weight gain or production a route was determined in units of displacement; then by using formulas of energetic measurement transform these to metabolizable energy which is a easily relatable unit with the energetic requirements of maintenance and production, 60 goats from different races were considered in this study, in which their weight and ages were recorded before forming part of the test. With the help of pedometers calibrated for use in goats, the usual route is determined. Pedometers were placed in one of his post-kneemembers, and retired after 24h, recording their movement and activities in search of food. Using Excel proceeded to the tabulation and organization of data, which were subjected to descriptive statistics and analysis of information, as a result of tours 5Km animal showed, aged 2.5 years average, similarly races more frequent goats were first Creole and secondly the Nubia; both breeds of animals did not differ in the way and weight, enabling use a universal way to estimate energy expenditure (0.49 kcal / kg / km) being able to determine which were involved in 24h 87,69Kcal activity.

Abstract The purpose of the study was to assess poverty in Serbia in the period 2006-2010. This paper analyzes the percentage of the poor by: type of neighborhood, regional distribution, household type, age, involvement of children and adults, level of education and socio - economic status of the household. The following methods of descriptive statistics were applied: the average value of the appearance, the interval of variation, standard deviation, coefficient of variation and the rate of change. It points to the differences in the values of consumer units denominated in RSD, which is used as a threshold for determining the percentage of the poor population. The research results indicate that the poorest are multi-member households and adults at the age of 19-24.

This chapter deals with quantitative analysis, and especially description and inference. It introduces the reader to the principles of quantitative research and offers a step-by-step guide on how to use and interpret a range of commonly used techniques. The first part of the chapter considers the building blocks of quantitative analysis, with particular emphasis on different ways of summarizing data, both graphically and with tables, and ways of describing the distribution of one variable using univariate statistics. Two important measures are discussed: the mean and the standard deviation. After elaborating on descriptive statistics, the chapter explores inferential statistics and explains how to make generalizations. It also presents the concept of confidence intervals, more commonly known as the margin of error, and measures of central tendency.
